Patent KR-20020079771-A (KR)
IPC: H05K3/42
Filed: 2000-11-16
Abstract: A composition and method for cleaning and conditioning a non-conductive surface defined by a through hole in a printed circuit board (PCB) is disclosed. The through hole surface is contacted with the composition of the invention to provide a cleaned and conditioned surface. The clean and conditioned surface is coated with conductive carbon particles (usually graphite) to provide a carbon-coated surface. The carbon-coated surface is electro plated and then soldered using hot solder. Those surfaces that have been soldered and also treated with the composition of the invention exhibit fewer blow hole problems. The composition of the invention comprises carbonates, binders, and resins, and combinations thereof, that improve the adhesion and coverage of a coating containing graphite to a surface defined by a through hole bore or other substrate. ("Through holes" as used herein refers both to through holes and to vias.)
